Innovative ophthalmic lens options enable eyecare practitioners to solve patients’ everyday optical problems.
Digital imaging gave us new designs and now there are amazing new lens treatments to go with them. In particular, I’ve found three recently developed lens treatments that solve vision issues which have plagued patients for quite some time.
In the past I would occasionally get a patient who mentioned she has a problem with her lenses fogging up. It was a rare patient complaint so I didn’t think much of this being a problem. With the advent of Essilor of America, Inc.’s Crizal UV™ Lenses with Optifog™ Technology, my practice added a question onto our patient history form, “Do you ever have a problem with your eyeglass lenses fogging up and causing temporary blindness?” I was surprised to learn the amount of patients who actually do!
There are numerous instances that cause patients’ lenses to fog up. A few examples include cooking over steaming pots, drinking hot beverages, eating hot food, skiing, jogging, and wearing safety and costume masks. Location is also a contributor. I notice fewer problems living in Southern California where it is dry, but when I travel to humid climates my lenses steam up and temporarily blind me.
Crizal UV Lenses with Optifog Technology is a new generation of lens innovation with an exclusive anti-fog property. When paired with the Optifog Activator, Crizal UV Lenses with Optifog Technology offer ideal protection against foggy vision. Patients can activate the anti-fog property by simply applying a drop of the Optifog Activator to each side of the lenses once a week to enjoy fog-free vision. The lenses’ anti-fog coating durably retains the Optifog Activator, preventing fog from appearing for up to one week.
Opticote, Inc. also ensures the quality of patients’ vision isn’t compromised by condensation. Its FOG FREE eliminates the “white wall” condensation that occurs during the transition between environments at different temperatures. This thermally cured fog-free coating leaves the wearer with uncompromised vision in even the most extreme fog-inducing conditions. It can be applied to uncut lenses that are plastic, polycarbonate, Trivex®
material , high-index, polarized, Transitions®, or Younger Optics’ DriveWear®—prescription or non-prescription.
|Virtually clear and non-polarized indoors, Transitions Vantage lenses darken outdoors and align themselves to polarize the light.|
Whenever patients wear polarized sun lenses, they never go back to non-polarized lenses. The improvement in vision and comfort is obvious to the wearer. Eyecare practitioners often mention the blocking of reflections off horizontal surfaces as the reason. Less understood is the fact that there is less “scattering of light” off horizontal surfaces—also improving the vision. The new Transitions Vantage™ lenses from Transitions Optical, Inc. offer both these advantages as well as changing tint for the ambient light conditions.
Transitions Vantage lenses start out virtually clear and non-polarized indoors. Outdoors, the photochromic molecules darken and align themselves to polarize the light. This can benefit everyone by blocking the specular reflections which occur off horizontal surfaces such as water or tabletops. In large amounts, specular reflections result in disabling and blinding glare. For patients with media changes, less scattering can even provide greater relief from glare and loss of contrast.
MAXIMUM UV PROTECTION
We can also improve patients’ lives through preventive medicine. UV light causes several changes that can affect how patients see as well as affect the appearance of skin around the eyes. A friend of mine, Neil Hodur, OD, Professor at Illinois College of Optometry, realized we may not be protecting patients’ eyes from UV reflections off the back of a lens. He conducted research and found not only does anti-reflective (AR) treatment not block UV reflections, it actually increased the amount of UV reflected. From that revelation, Crizal SunShield UV™ from Essilor was developed as the only AR that also blocks UV reflections from entering the eye and striking surrounding tissues.
When I now see patients for their annual eye exam, I explain, “A company has developed a sun lens feature called Crizal SunShield UV, which is the only one that blocks the reflections of UV onto the eye from the back of a lens. That means all over-the-counter sunglasses don’t provide full protection to your eyes—you can currently only get this protection from prescription lenses. We’ll prescribe SunShield UV on your lenses today to give you the maximum protection from the harmful UV light.”
By using this explanation, all of my patients are eager to get the extra protection. In addition, Crizal SunShield UV offers ideal backside scratch resistance and stays cleaner for a longer period of time.
|INTRODUCING SHAW LENS Optometrists can further improve patients’ comfort with SHAW™ lens. Sold only through optometrists, Shaw Lens Inc.’s patent-pending design accommodates the way both eyes work together to solve aniseikonia.
“The basic problem with current lens design is that it doesn’t take into consideration how both eyes work together,” said Peter Shaw, OD, Inventor and Co-founder, SHAW Lens. “This often results in unequal image size (static aniseikonia) or different demand on motor fusion (dynamic aniseikonia) between the eyes. This can be as uncomfortable as uncorrected vision.”
SHAW Lens is a start-up company that debuted its lens at this year’s Vision Expo East. Peter’s brother, Michael, is President and said the company is operating as its own lab and selling lenses directly to optometrists. The free lens design software can be downloaded at shawlens.com. Optometrists then enter the motor fusion limits, frame dimensions, and patient’s prescription. The software applies ray tracing algorithms to design lenses that solve static and dynamic aniseikonia to within the patient’s limits. SHAW Lens has partnerships with several labs to manufacture lenses that can be delivered to optometrists within 10 business days.
“How we manage aniseikonia is what we’re all about,” commented Michael Shaw.
When combined with polarized or tinted lenses, Crizal SunShield UV provides patients with maximum protection to help shield against UV-related diseases, such as macular degeneration, cataracts, and pterygium. We sometimes forget that tissue damage is caused by the sun’s energy, which can be absorbed by molecules. The molecules have electrons orbiting that may get knocked out by the light energy. This energy absorption results in an unstable molecule referred to as a “free radical.” The free radicals bump into other molecules composing cell membranes and tissue trying to get stable. They join with the tissue changing the composition. This is a simplified explanation on how cataracts and lid neoplasms form. By reducing the amount of light hitting the eyes and surrounding tissue, practitioners help prevent the incidence of many eye disorders.
Because the mentioned lens treatments have the power to improve the lives of patients, prescribing these treatments can turn satisfied customers into enthusiastic patients who are eager to market your practice through word of mouth.
